ROTARY ENGINE.

SPECIFICATION forming part of Letters PatentY No. 716,589, datedDecember 23, 1902.

Application filed December 14. 1901. Serial No. 85.885. (No model.)

To @ZL w/wm/ it may concern:

Be it known that we, JOHN SPRINGER and WILLIAM A. RoBBINs, citizens ofthe United States, residing at Trenton, in the county of Mercer andState of New Jersey, have invented certain new and useful Improvementsin Rotary Engines, of which the following is a specification.

This invention relates to rotary engines, and has for its object toprovide au engine of this character of simple construction and increasedefficiency.

Another object of the invention is to provide an engine of thischaracter wherein there will be a continuous exertion of pressure uponthe driving-shaft.

Another object of the invention is to provide a rotary engine having nodead-center.

Another object of the invention is to provide an improved valve for acut-ofi'.

Another object of the invention is to provide an improvedgovernor-controlled cut-oif for rotary engines; and another object ofthe invention is to provide an improved pistonwheel for rotary engines.

In the drawings accompanying and forming a part of this specification,Figure 1 is a vertical central longitudinal section of a form of ourinvention; and Fig. 2 is a sectional view, at right angles to Fig. 1,taken on the line Ct a thereof. Fig. 3 is a perspective view of a formof valve. Fig. 4 is a diagram of the valve-port. Fig. 5 is a perspectiveof one of the piston-wheels and associated parts. Figs. 6, 7, and S arediagrammatic views on the plane of Fig. 2, but to a smaller scale,showing the operation of the parts. Y Y

The engine is shown as mounted upon a suitable bed, (designated in ageneral way by A,) to which is secured a suitable housing (designated ina general way by B) and which is shown as embodying end plates 7 S and acentral plate 9, substantially parallel with the end plates, to whichplates are secured rings 10 10, constituting housings andexpansionchambers for the piston-wheels 11 1l, which wheels are rigidlymounted upon a drivingshaft 12, having suitable bearings 13 in housings14, secured to the end plates, shown as conoidal in form and having thejournals in the apexes. Each wheel is shown as prowheel immediatelybehind the piston.

vided with two pistons 15, freely sliding in chambers 16, (shown astangential,) each of which chambers is in communication by means of aninlet-port 17 with a valve 18,10- cated in a chamber 19 in thepiston-wheel and affording access to a centrally-located fluidchest 20,receiving its fluid from the source of supply through the port 21. Theiiuidchest 2O is shown as located between the piston-wheels. Connectedwith the inner end of each of the piston-chambers is a channel 22,communicating with the perimeter of the Two concentricexpansion-chambers (designated in a general way by C O) are shown asprovided between the perimeter 11' of each of the piston-wheels and theinner perimeter 10 of the housing l0, which are shown as havingdiametrically oppositely disposed exhaustports 23 23, communicating withsome suitable point outside of the housing. Atashort distance ahead ofthe exhaust-port an incline 24 is provided upon the housing 10, uponwhich inclines the pistons ride up and are pressed into thepiston-chambers, whereupon they will cut off or throttle the channel 22,and immediately thereafter the pistons will ride past the exhaust-portsand permit the cylinder to exhaust, a portion 25 ofthe face of thehousing immediately past the exhaust-port being in engagement with thepiston-wheel, thus bringing the piston completely within the wheel atthat point. An inclined plane or face 26 leads away from such point ofengagement, permitting the piston to slide out from its'chamber underthe pressure exerted upon its upper end, it being held constantlyagainst the outer working face of the expansion-chamber by suchpressure. The incline 26 may, if desired, be made more abrupt than theincline 24. The inclines 211 and 26 and face 25 form a cam-face. Uponthepiston being pushed down by the fluid expansion the fluid may passthrough the channel 22 and exert its expansive pressure upon the piston,expanding between the piston and the face 26, which takes the place of acylinderhead. It will be seen that the piston not only acts as a piston,but also as a cut-off or throttle. The fluid in the piston thereby isprevented from escape; otherwise the iiuid IOO back of the piston wouldexhaust and the incoming fluid would expand unnecessarily, causing aWaste.

The valves 18 are shown as each composed of a hollow cylinder 27, openat one end 28 and provided at the perimeter with a triangular opening29, a diagram thereof being shown in Fig. 4, having one side 30 parallelto the axis of the cylinder and one side 31 substantially transversethereto, Which opening leads from the outside into the hollow interior32, the open end of the cylinder being in communication with thefluid-chest 20 and forming an inlet-port, the organization being suchthat the side 30 of the triangle will coincide with the side of theinlet-port 17 for the piston. The valves are shown as providedwith stems32', passing through suitable adjustable stuffing-boxes 35 and glands36, having packing 37 therebetween. The valve-stems are provided withjournals 37', having bearings 38 on wings 39 of a collar 40. Thedriving-shaft journals are shown as provided with bushings 41, securedin the housing by setscrews 42, each bushing extending inwardly in theform of a sleeve 43, upon which sleeve a gear-wheel 45 is looselymounted and capable of reciprocation thereon. The gear-wheel is providedwith a hub or sleeve 45', upon which is freely mounted a collar 40, heldfrom reciprocation on the sleeve 45' by a ring 46', held in place on thesleeve or hub by setscrews. Each Valve-stem is provided with a pinion46, in mesh with the gear-wheel 45, the organization being such thatupon the revolution of the piston-Wheels and shaft the pinions will berotated by the stationary gear- Wheel and rotate the Valves, and theopenings in the valves and valve-.chambers will be caused to register toform ports and on further rotation to cut olif. In Fig. 5 the uppervalve is shown in a position relatively to the opening in its chamber toproduce a fullsized port, the position of the piston being shown at thebeginning of its stroke. The fiuid will be gradually out off by means ofthe spiral conformation of the port of the Valve, so that upon thecompletion or approach to completion of the stroke of the piston thefluid will be entirely cut off.

The ring 46' may be engaged by points 48 of a yoke 49, which yoke issecured upon a rock-shaft 50, projecting out through the housing toeither a governor or some other suitable operating device. If the engineis running too fast, upon the rocking of the shaft a predetermineddistance the yoke will be moved, thereby moving the valves in adirection from the stuffing-boxes and will thereby diminish the area ofthe ports formed by the openings in the valves and the openings in thechambers and cause the valves to cut off sooner. Upon the reduction ofspeed the valves will be moved back toward their full port and normalcut-off position. Each side of the piston-wheels is shown as providedwith suitable annular channels 51, in which suitduction port; expansionchambers; and a cam-face in each expansion-chamber effective to actuateone 0f the throttling means.
